To all whom it'may concern:

Be it known that I, Dorm H. MONTGOM- ERY a citizen of the United States, residin at lDenver, in the county of Denver an State of Colorado, have invented new and useful Improvements in Springs for Motor- Vehicles, of which the following is a specification.

The present invention is directed to improvements in springs for motor vehicles.

The primary object of the inventlon is to provide a spring gear for motor vehicles so constructed and arranged that the shock and jars usuall transmitted to the chassis, and thence to t e body, from the wheels, are reduced to a minimum.

A further object of the invention is to provide a vehicle spring of this natureso constructed that it will last praotically'indefinitely, the same being extremely simple in construction, and consequently cheap to manufacture.

A still further object of the invention is to provide a spring of this character so constructed that each spring unit is so associated with the adjacent unit that the rebound of one will be counteracted by the remaining spring units.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanyin drawings, in wh1ch:

Figure 1 is a p an view of a motor vehicle frame showin ciated therewit Fig. 2 is a longitudinal sectional view through the same.

Fig. 3 is a sectional view on l1ne 3-3 of Fig. 1.

Fig. 4: is a rear elevation.

Fig. 5 is a detail perspectlve view of one of the front connectlng links.

Fig. 6 is a similar view of the rear connecting lever.

Fig. 7 is a sectional view through the ball and socket connection.

Referring to the drawings, 1 designates the chassis frame, which comprises side sills 2, the rear ends of which are rigidly connected by a transverse bar 3. These sills are preferably hollow and angular in cross section, as shown in Fig. 3 of the drawings.

The front axle & may be of any shape in cross section desired, and has rigidly at- Specification of Letters Yatent.

tached thereto the inner ends of the arms 5, two of which are employed,-said arms being slightly curved, and have their outer ends pivotally connected, as at 7, to the forward ends of the sills 2.

SInce the springs and their connections associated with the sills 2 are identical in construction and arrangement, the description of one will sufiice for both.

Suitably secured to the front axle 4: are plates 8, which are provided with ears 9, said ears having pivotal connection with the links 10, and pivotally connected between the links 10, as at 11, are the forward ends of the semi-elliptical springs 12. These springs are provided centrally with clips 13, said clips being pivotally connected with the bolts 14; which are suitably mounted on the sills 2.

A cross bar 15 is employed and has its ends sultably secured to the sills 2, said bar being provided with a central bolt or the like 16, and pivotally connected to the bolt 16 1s a transversely disposed rocker arm 17, the urpose of which will appear later.

T e springs 18 have clips 19 attached to their central portions, and these clips are ivotally connected to the bolts 20 carried y the sills 2.

The -ends of the rocker arm 17 are formed with balls 20, said balls being engaged in sockets 21 carried by the bell crank levers 22, the arms 23 thereof being pivotally connected to the rear ends of the springs 12, as at 24, while the arms 25 are similarly connected, as at 26, to the forward ends of the s rings 18, as clearly shown in Fig. 2 of the rawings.

Rock levers 27 are employed, and are formed with central bearings 28 for engaging the rear axle 29. The forward ends of the levers 27 are pivotally connected between the links 30, which are in turn pivotally connected with the rear ends of the springs 18. To the rear ends of the levers 27 are pivotally connected clips 31, said clips having rigidly connected thereto bolts 32, and to which are pivotally connected the ends of the semi-elliptical spring 33. The spring 33 is provided with a central clip 34: which is pivotally connected with the trans verse bar 3. Thus it will be apparent that all springs are connected in such relation that a shock imparted to one will be transmitted to the others, and owing to the presence of the rocker arm 17, and the rear spring 33 shocks will be absorbed from one set of side springs by the other set on the op osite side.

t is obvious that should one of the front wheels, for example, the right hand one, strike an obstruction the axle 4 w1ll move upwardly, whereupon the ad acent spring 12 will rock on its pivotal polnt, thus causlng the rear end to move downwardly with the result that the associated bell crank lever 22 will rock so that the arm 25 thereof w ll compel the alined spring 18 to rock on lts pivotal connection. When this occurs the rear end of the spring 18 moves downwardly, thus rocking the lever 2?, whereupon the rear s rin 33 1s rocked in an ob- VlOllS manner with t e result that the shock is transmitted to the set or pair of springs on the opposite side of the frame.

What is claimed is 1. The combination with a vehicle frame and its'associated front and rear axles, of springs pivotally connected 1n pairs w1th the sldes of the frame, and pivotally connected with the respective axles, and means ivotally supported transversely of the rame for pivotally connecting the ad acent ends of the paired springs.

2. The combination with a vehicle frame and its associated front and rear axles, of a pair of springs pivotally connected with the sides of the frame, arms rigidly connected to the front axles and pivotally connected with the frame, and a rocker arm pivotally supported transversely of the frame and pivotally connecting the adjacent ends of each air of s rin 3. he comblnation with a vehicle frame and its associated front and rear axles, of springs pivotally connected to the sldes of the frame and longitudlnally thereof, a s ring pivotally supported transversely of t e frame, means pivotally supported by the rear axle for pivotally connecting one setof the side springs and the transverse spring, means carried by the front axles for pivotally connecting the other set of side springs to the frame, and means for pivotally connecting the adjacent ends of the side springs.
